Subject: Question about SWIGing a C++ array for Ruby

	I've got these C++ classes:

class CSITick {
  public:
   unsigned long date;
   float open;
   float high;
   float low;
   float close;
   long volume;
};
class CSIChart {
  public:
   CSITick* getTick(long date);  // CAN return NULL!!!
   CSITick* ticks;
   long numticks;
   //...
};


where 'ticks' is an array of CSITick's, created with:
   ticks = new CSITick[numticks];

	I can't seem to figure out how to make SWIG access this
'ticks' pointer as if it were an Array in Ruby, with length
equal to numticks.  I would like it to be read-only as well.

	The '%typemap' SWIG directive doesn't seem right, as
this is the only place where I want to treat a CSITick* as an
Array... otherwise, I would like a CSITick* to just be a reference
to an instance of CSITick.  Am I making any sense?

	I'm using SWIG-1.3.17 and ruby 1.6.8 (2002-12-24) [i586-mswin32]
on Windows XP.

	Thanks!
